-Hominids were the first species to modify stones to make tools out of and manipulate objects to get what they want.
-Hominids used stone flakes and rock cores presumably for chopping and scraping/ or used naturally sharp rocks.
Homo Sapiens:
-Prehistoric homo sapiens didn't only make and used stone tools, they specialized them and made a variety of smaller, more complex and refined. These specialized tools included stone tools, fishhooks and harpoons, bows and arrows, spears throwers and sewing needles.
Neanderthals:
-Neanderthals were masters of the new-tool making technique, making spear points with stones or a soft hammer. There were traces of adhesive in some stone points suggesting they were attached to wooden shafts, perhaps glued with resin or tar and bound with plant fibers, sinew, or leather]]> 2018-05-11 20:18:21 UTC https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260077347 gwendelyn_waller https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260077727 Variation

The early hominids first migrated around 1.8 mya from Africa, there they first migrated over to the Levantine corridor and the Horn of Africa to Eurasia.
Homo sapiens/ Neanderthals:
They migrated from Africa to the coasts or southern Europe, and either moved more north or moved into Asia spreading outwards leading to Australia and the Americas. ]]> 2018-05-11 21:37:40 UTC https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260088434 gwendelyn_waller https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260634021 Convergent evolution is the process whereby organisms not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
Some examples of organisms that share convergent evolution traits with humans:
Human and squid eyes
Human and insect ears
Birds and human speech
Opposable thumbs and other primates
Fingerprints in humans and koalas
Higher intelligence in birds and primates]]> 2018-05-14 20:23:23 UTC https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260634021 gwendelyn_waller https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260645072 2018-05-14 21:08:16 UTC https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260645072 gwendelyn_waller https://padlet.com/gwendelyn_waller/9h96syh815sp/wish/260647474 Vestigial organs are organs of the body which are smaller and simpler than those in related species.
